摘要
为了在更大范围内实现数据集成,提出一种基于本体的数据查询描述模型.通过将信息提供类web服务描述为访问模式受限的数据视图,使该模型能像普通的resource description framework(RDF)数据源一样用来回答数据查询.同时给出相应的查询—数据源匹配算法.基于web服务动态调用技术,设计了1个集成这2种数据源的数据集成系统,并实现了原型对其可行性进行的验证.
Aimed at data integration in a larger extent, an ontology-based description model of data query is put forward. By depicting information-providing web services as data views with limited access pattern, the model enables them to answer data queries as ordinary resource description framework （RDF） data sources do. The matching algorithm of corresponding query-data sources is presented. Based on the dynamic invocation technology of web services, a data integration system is designed which combines such two kinds of data sources. And a prototype is implemented successfully through which the feasibility is validated.
